How long does it take to build a ground floor extension?

The timeline for a ground floor extension typically ranges from 8 to 16 weeks once construction begins, depending on the size and complexity of the project. A simple single-room extension might take 8-10 weeks, whilst a larger open-plan extension with kitchen and bathroom work could take 12-16 weeks or more.

Several factors influence the construction timeline, including weather conditions, complexity of structural work, availability of materials, and the extent of internal fit-out required. Extensions requiring significant electrical or plumbing work, custom joinery, or specialised finishes will naturally take longer to complete.

It's important to note that this timeframe covers only the construction phase. The pre-construction phase, including design, council approvals, and obtaining building permits, typically adds another 8-12 weeks to the overall project timeline.
